Analysis of the Arabidopsis V-ATPase reveals convergent evolution of differential targeting as well as redundancy of the endosomal and vacuolar isoforms during vegetative development.
An unbiased genome-wide human forward genetic screen identifies the vacuolar ATPase complex and assembly factors as regulators of HIF stability through their actions on intracellular iron metabolism.

Impaired lysosomal acidification results in retention of iron inside lysosomes, triggering functional iron deficiency, dysfunctional mitochondria (especially mtDNA loss), and inflammation in vivo in a mouse model of lysosomal disease.
Multicellular and socially aggregating prokaryotes contain previously undescribed, chaperone-based systems predicted to mediate defensive biological conflicts, several components of which are thematically similar antecedents of eukaryotic apoptosis pathways.

In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.
